AI Agent Frameworks

Frameworks are the libraries and runtimes you build agents with. Each profile covers what the framework does, what it deliberately does not do, how setup looks, and which tools in this directory have a sourced compatibility record with it. Compatibility is never inferred from a shared category: every pairing links to the evidence behind it.

5 verified framework profiles. How we verify: read the methodology.
